1 . A housing case for a small electric device and communication device, the housing case comprising:
 a flat plate having a dimension substantially the same as that of a front portion of the housing case and comprising at least a glass plate; and   a resin frame integrated with the flat plate to support a backside periphery of the flat plate.   
     
     
         2 . The housing case according to  claim 1 ,
 wherein the flat plate has decoration on a rear surface of the glass plate.   
     
     
         3 . The housing case according to  claim 1 ,
 wherein the device includes a display device; and   the flat plate has decoration on the front surface and/or the rear surface of the glass plate except at least a display window for the display device.   
     
     
         4 . The housing case according to  claim 1 ,
 wherein the rear surface of the glass plate is not decorated; and   the rear surface of the glass plate is integrated with the resin frame, with an adhesive layer for glass, a primer layer, and an adhesive layer for resin interposed between the rear surface of the glass plate and the resin frame.   
     
     
         5 . The housing case according to  claim 3 ,
 wherein the rear surface of the glass plate is decorated,   the layer having the decoration also serves as an adhesive layer for glass in the portion where the rear surface of the flat plate is integrated with the resin frame; and   the rear surface of the flat plate is integrated with the resin frame with a primer layer and an adhesive layer for resin interposed between the rear surface of the flat plate and the resin frame.   
     
     
         6 . The housing case according to  claim 1 ,
 wherein the flat plate has an opening.   
     
     
         7 . The housing case according to  claim 6 ,
 further comprising an opening resin frame integrated with the flat plate to support the surrounding portion of the opening.   
     
     
         8 . The housing case according to  claim 1 ,
 wherein the resin frame covers a side surface of the flat plate.   
     
     
         9 . The housing case according to  claim 1 ,
 wherein the integrated flat plate and resin frame has a box shape.   
     
     
         10 . The housing case according to  claim 1 ,
 wherein the resin frame supports the entire backside periphery of the flat plate.   
     
     
         11 . The housing case according to  claim 1 ,
 wherein the resin frame supports one, two, or three sides of the backside periphery of the flat plate.   
     
     
         12 . The housing case according to  claim 1 ,
 wherein a plurality of divided portions of the resin frame support the backside periphery of the flat plate.   
     
     
         13 . The housing case according to  claim 1 ,
 wherein the resin frame is made of a resin material having a molding shrinkage rate of 0.6% or lower.
